152 THE BROWN-TAIL MOTH. 
next to the bark of the tree to prevent the ink from injur- 
ing the tree and the ascent of the caterpillars in the crev- 
ices of the bark beneath the paper. 
This banding will not, however, prevent reinfestation by 
the winged moths, which fly to them and deposit their egg 
clusters in July, so that it is not as efficient as in the case 
of the gipsy moth, which does not spread by flight, and 
which makes apparent the necessity of destroying the in- 
sect in its immature stages as far as possible, so that the 
winged moths may not spread, if its numbers are to be 
reduced from year to year. 
Destroying Pupce. — Late in June and early July the 
cocoons containing the pupae may be gathered, though it is 
likely to be attended with severe inflammation of the skin 
from the nettling hairs if precautions are not taken. Such 
cocoons* or pupa? should be placed in a barrel or box covered 
with mosquito screening so that the moths are confined but 
any parasites which develop may escape through the screen. 
Destroying the Moths. — Often the electric light and tele- 
graph poles near lights are covered with the white-winged 
moths, in which case they may be largely destroyed by 
washing down with a stiff jet of water from the hydrant 
hose. A spray of pure kerosene or kerosene emulsion may 
also be found desirable under some circumstances for de- 
stroying the moths. 
NECESSITY OF THE CONTROL OF THE BROWN-TAIL MOTH. 
In the southeastern corner of the state, where the brown- 
tail moth has now become abundant, everyone is impressed 
with the importance of doing everything possible to sup- 
press or control it, as are those persons who have been un- 
fortunate enough to have visited in the infested district in 
Massachusetts during the caterpillar season. In general the 
New Hampshire public seems alive to the necessity of the 
control of the pest. 
Under the law passed in 1907 it now becomes incumbent 
on every property owner to remove and destroy the winter 
nests on his trees up to a cost of one-half of one per cent 
of the taxable valuation of the property. It is incumbent 
on the selectmen of towns and mayors of cities to see that 
this is done or to have the work done at the expense of 
the town and city and charge same to the taxes of the negli- 
gent property owner. If the selectmen or mayors fail in 
their duty, they may be compelled to act by the governor 
and council. The law seems ample to ensure that everyone
